Enables GABA-A receptor activity and chloride channel activity. Involved in response to xenobiotic stimulus. Predicted to be located in postsynaptic membrane. Predicted to be part of GABA-A receptor complex. Predicted to be active in GABA-ergic synapse; dendrite membrane; and postsynapse. Predicted to be integral component of synaptic membrane. Orthologous to human GABRG3 (gamma-aminobutyric acid type A receptor subunit gamma3). [provided by Alliance of Genome Resources, Apr 2022]
